The actress and husband Brian Austin Green have welcomed their second child together, another baby boy, People reported Thursday.

Their new addition joins brother Noah, 16 months, in the family fold. Green is also dad to 11-year-old son Kassius from a previous relationship.

Fox has been pretty quiet on the social media front in recent weeks, though she did post an illustration on Facebook Tuesday of a woman sitting peacefully under a tree, looking up at a single shining star. Then again, it could also be the sun. Or son...

The Teenage Mutant Ninja Turtles star's rep confirmed in August that the couple were "very happy" to be expecting again. Fox was most recently spotted in public (well, more like in the driveway of their house) by paparazzi earlier this month, when she was packing up the car for an outing with Green and Noah.

Fox admitted back in November that she had a tough first trimester, just as she did during her first pregnancy.

"But once you get into the second, it's fine after that," she told ABC News.

She also didn't have time to dwell on which pregnancy was harder than the other. "I don't have time to think about it," she said. "I have a 1-year-old running around. And then when you're working, like, 16 hours a day, there's no time for you at all. When I was home, I wasn't sleeping. I was trying to make out time for the baby and spend time with him. So it was rough."

But not long before giving birth to baby No. 2, Fox was gearing up for a romantic Valentine's Day—or, with her due date nearing, at least gearing up for the launch of Avon Instinct for Her and Him.

"The for Her scent is perfect for women who want to feel confident, beautiful, and sexy," the spokesmodel described the scent in a statement. "If you need a gift for the special man in your life, I would recommend Instinct for him. When I met my husband, the chemistry between us was magnetic. I love Instinct for Him because it captures that powerful moment of seduction—electric and intuitive—that sparks overwhelming passion without even saying a word."

Well, she and Green obviously managed to keep the fire burning after their first child was born.
